Question

If amount of DNA in sperm cell is 10 picogram, then what will be amount in microsporocyte in an phase of the cell cycle?

• A. 10 pg
• B. 20 pg
• C. 80 pg
• D. 40 pg

Answer 1

The correct option is B 20 pg

• Microsporocytes, which are diploid cells capable of undergoing meiosis to form a tetrad (four joined cells) of haploid microspores. The microspores become pollen grains and may eventually separate.
• As we know the sperm(or male gametes) are haploid. The amount of DNA in this gametes is 10 picogram. Therefore, the amount of DNA in microsporocyte will be double i.e, 20 picograms.

So, the correct answer is " 20 pg ".
